Application med July 7,

This invention relates to improvements in'.

gravity oilers for pressure waterv p umping systems, and is particularly intended foruse in `connection with a deep well pumpapparatus which includesva turbine in the'well and a drive means mounted in connection with the discharge head of theV well casing directly above'the well. In apparatus ofthis character the oil is fed to the pump by gravity from above ground 'and a form of oiler commonly used is of the 'manually controlled sight feed type. With this type of oiler the attendant must close lthe oiler every time the pump isstopped, as other wise the oil will continue to flow and a considerable waste will of course be had.r

Automatically-operated oilers are also on the market, includin .one operated lby electricity, a mechanica ly operated one, and ,one known as the velocity type which also requires powerfor its operation. All such' such devices using up power,

'are somewhat complicated and expensive. The principal object of my invention is to produce an automatic oilerfor the purpose arranged to loe-operated bythe water vkpressure generated pump, and as such pressure is created and is available whenever and onlyl when the pump is operated, no power is used in operating the oiler, and thereis nocost to the user other than the initial cost of the device itself. A further object of the invention is to provide adevice forthe purposewhich may be readily installed in connection with a standard pump drive unit. i j n A Another object is to provide means for enabling the amount of oil fed from the oiler to be easily regulated while `ope-rating with a constant pressure and without interferingr n with the functioningV of suchv pressure.'

A further object of the invention is topprovduce a simple and inexpensive device andyet one which will be exceedingly effective for the purpose for which it is designed.

These obj ects I accomplish by means of relative arrangement of partsas will fully appear by a perusal of the following specification and claims. "i

system showing my oiler installed in conf nection therewith. Fig. 2 is an enlarged longitudinal section `of the oilertaken on the line 2-2 of 1. Referring now vmore particularly tothe the drawings,the to which my yoiler pump driving structure is applied lincludes a discharge head 1 through vwhich the water under pressure passes, a tubular support or standard l? projecting upwardly from the discharge head and a driving motor 2 mount-eden said standard. The motor hasa shafty 3 depending therefrom to the pump below 'and enclosedin a sleeve 4 having-a capl on its upper outwardly from the capv 1s which thel oiler of whatever character 1s emend. Projecting` My oiling device, to' be connected tosaid pipe 6, comprises a body 7 preferably of rec tangular'form andv of suitable capacity. The

body is adapted to be supported a short dis-V tance above the pipe ard vlu-by means of brackets 8 attached to and projecting upwardly fromv said standard, the body at its ends having feet 9 'to rest on` and be, secured to said brackets.

Projecting upwardly through the body is lower end to engage a gaslret-l2placed against the bottom of the body.` Y A on the top of the tube above the body to draw the head'll snugly against itsgasket. If desired or foundA necessary a Vspacer sleeve 14 may be placed about the tube 10 between the prevent inward opposite faces of the body jto deflection of the body walls when the nut 13 sleeve 'and tube adjabody'haveradial Land 15 leading. from Y. the body to the interior' ofthe tube.

. -The member 10 adjacent its lower end and below the openings 15 is formed with a'n up'- wardly facing valve seat 16 to cooperatewith cent 4the bottom ofthe pressure-means for moving the lever in a valve opening direction.y a glass tube 21 being kfitted to the inside of the element 2O in any This proarrangement enabling the oil dropping' fromv the tube 10 to be readily seen.v The lowervv tapped as at'22 to receive the upwardly prof ecting nipple 23 which is securedto the outer endofthe oil pipe 6. e v v The presfnireA actuated means for taper-ating nut 13 is threaded 6 and Voutside the standl end of the element 20 is the stem 17 comprises an enclosed casing` 241 mounted at oneend of tliebody. Extending across and secured to the casing in clearance relation .to the front and back of the same `is K a diaphragm 25 of suitable material, preferablya composition of rubber and canvas. The casing outwardly of the diaphragm is arranged for connection to the upper end ol ofl the casing for engagement with one end ofl a lever 28 pivoted intermediate its ends onto said casing. rlhe arm of tlielever engaged by the pin passes between the casing` and the body 7; rthe other arm beyond the Ypivot extendingv over the body 7 for a certain distance, being then bent upwardly and vfinally horizontally toward the stemv 17. At such yend the lever is forked as at29 for engagement with a grooved sleeve 30 slidably mounted on the stem 17 above the cap 18. A normally slack stiff compression spring 31 is mountedl onthe stem above said sleeve, one endof the vspring bearing against the sleeve and the `other end against a collar 32 fixed on the up-V per end of the stem. The stem 17 also has a collar 33 fixed thereon between the sleeve 30 and the cap 18 and another fixed collar 34:

.below the cap. i 1

Formed with the casing 24 and overhanging the upper portion of -the lever 28 is a .bracket 35 in which is mounted an adjustable .screw 36 to engage said lever; a compression Y spring 37 .being disposed about said screw and.

bearing against the bracket and lever.

lnA operation when the pump is idle and no water underpressuie is passing through the head 1 and pipe 6 the diaphragm is relaxed and the spring` 37 a'ctson .the lever 28 to force the diaphragm outwardly or toward the pipe j 26 and also to force the sleeve 30 against the collar 33,depressing the stem 17 and closing the valve. No oil then passes through the body. henl the pump .is driven and water is passing` through the head 1 and pipe 6, the Tdiaphragm is acted on by the water and the" lever is acted on to cause the resistancezof the spring 37 to be overcome and the collar 30 to be' raised, until the lever abuts against the limiting screw 36. `Raising of the sleeve 30 acts through the spring 31 and collar 32to lift vthe needle valve off its seat, allowing the ,.oil to flow from the body by gravity. The

vextent of opening of the stem irrespective of the movement of the lever 28, is governed by adjustment of the cap y18 which limits the l upward movement ofthe stem by reason 4of the collar 34v abutting against the cap after a certain amount of upward movement of the time further movement of'thelever and sleeve 30 can be had without straining any part by I reason of the compression of the spring .31

From the foregoing description itwill bel readily seen that I have produced such a' .de-

vice as substantially fulfills the objects of?? `the invention as set forth herein. c
